Jen wakes up at 4:51 in the morning to start getting ready to leave for work. I wake up too, but then go back to sleep for another 40-50 minutes. Normally she snoozes for 5 minutes, playing the high stakes game of changing her alarm setpoint instead of hitting the snooze.
This morning…
Alarm
Me: Hey!
Jen: Hello, honey!
Me: I had a dream you just told me I was breaking the laws of thermodynamics.
Jen, encouragingly: I did?
Me: Uh huh.
And she got up without snoozing. Me? I snoozed three times and didn’t get up till after 6.
Words 
Why on earth 4:51??
hahahaha That is such an excellent idea. Will have to try any sort of thinking-is-required comment for morning alertness — maybe NPR is better for alarm clock radios than a Top 40 station?
